4.2 General Device Operation
After switching on the device (1), the display (4) shows the “Surface Concept” animated logo, while the
device is scanning for available modules and their specific settings. This can take up to several seconds.
If the device is ready for operation, it switches into the standby mode and shows an empty mask for the
voltage adjustment (see
).
Push the “Start/Standby” button in the lower left
corner of the display to switch on the high
voltage.
Alternatively one can press the “Channel” control
knob.
After switching on the high voltage the device
is in the so called operation mode. In operation
mode the display shows the name of the selected
channel in the top line (in this case “HV 1”) as well
as the output voltage of that channel.
The different HV channels can be selected by
turning the “Channel” control knob.

Figure 4: Operation mode – voltage adjustment.
The “Adjust” control knob is used to adjust the
output voltage. Turn the “Adjust” control knob
clockwise/counterclockwise to increase/decrease
the value of the output voltage in a step width as
defined in the line “edit step”.
The line “set value” displays the nominal value
for the output voltage as adjusted by the user.
Voltage adjustment can only be made in this line.
The line “actual” displays the actual value for the
output voltage on the output connector as measured by the device. The device always regulates the actual
value of the output voltage to fit to the nominal value as set by the user. Hereby the voltage measurement
is always a relative measurement between the two HV outputs of one channel. Additional reference
voltages (e.g. in floating operation) are not measured and therefore are also not displayed (see the manual
of the specific module for further details). Turn the “Adjust” control knob clockwise/counterclockwise while
pushing it to increase/decrease the step width in the line “edit step”.
Push the „Start/Standby“-button in the lower left corner of the display again to switch back to
the “Standby” mode.
